Differential diagnosis

The male resembles that of P. lamottei sp. nov. in having a similar sinusoid shape of the anterior lobe of the bulb, but may be recognized by the presence of a short spike at the base of the lobe on its prolateral side (compare Fig. 13C with Fig. 1C ). The female is similar to that of P. perezi comb. nov. in having the epigyne with a V-shaped anterior depression, but may be distinguished by the atrial area narrower than the area occupied by spermathecae ( Fig. 15A ), quite the opposite to that of P. perezi comb. nov. ( Fig. 8A–C ).

Description

Male

DIMENSIONS. Cephalothorax: length 1.7–2.2, width 1.4–1.9, height 1.0–1.3. Eye field: length 0.9–1.3, anterior width 1.4–1.7, posterior width 1.2–1.5. Abdomen: length 1.5–1.8, width 1.2–1.5.

COLOUR AND BODY. General appearance as in Fig. 14A–B . Carapace brown, eye field blackish, anterior median eyes encircled by fawn scales. Some brown bristles near eyes of anterior row, white hairs form wide pale band on slopes of carapace. Clypeus with white hairs. Abdomen dark, greyish brown with light herring-bone pattern becoming in chevrons posteriorly, venter yellowish or greyish. Long brown bristles on anterior edge of abdomen.Anterior spinnerets yellow, posterior grey. Legs yellow with brown rings, femora brownish. Leg hairs and spines brown.

GENITALIA. Pedipalps clothed in dense whitish hairs. Palpal organ as in Figs 13A–G , 14 C–F . Retrolateral tibial apophysis blunt and wide, dorsal apophysis narrow perpendicular to retrolateral. Bulb triangular with narrowing anterior lobe. Sharp spike on prolateral side of this lobe at its base ( Fig. 13A, C, F ), retrolateral margin of the lobe strongly sclerotized basally ( Fig. 13B, E ).

COLOUR AND BODY. Similar to male, abdomen slightly clearer, pattern with less contrast. Legs yellow with brownish rings at bases and ends of segments.

GENITALIA. Epigyne rounded with strongly sclerotized anterior part ( Fig. 15A–C ). Internal structure as in Fig. 15D , distinctly sclerotized edge around atria, spermathecae relatively large, accessory glands connected visible.
